soil microorganisms and plants together form a stable dynamic system in which they interact and influence each other. the growth and development of plants provide nutrients to the soil microorganisms, which in turn promote and contribute to the growth of plants. in addition, microorganisms are the most active components of the soil. they are diverse and numerous, and each performs a unique function in the soil ecosystem. different soil environments will develop different microbial population structures. therefore, in this paper, i will verify the relationship between soil microorganisms and temperature by measuring and analyzing the microbial biomass at specific locations for a stand of bamboo phyllostachys praecon.
